Two equations are often used to describe population growth: What is the difference between the solutions of these two equations, N_t and ∆N? A) N_t is the total population at time t; ∆N is the change in population over a time period. B) N_t is the change in population over a time period; ∆N is the total population at time t. C) Both show changes in population size, but only N_trepresents a population growth rate. D) Both show changes in population size, but they are based on different time intervals. E) Both show changes in population size, but they are based on different starting population sizes.

N_t represents the total population at a given time t, while ∆N represents the change in population over a time period. Therefore, the difference between the solutions of the two equations is that N_t gives the actual population size at a specific time, while ∆N represents the difference between the population size at two different times.
